|Laser-induced Hypopigmentation||Device: 810 Diode Laser||Phase 1|
Preoperative and postoperative photographic and clinical observations about the gingival melanin pigmentation were made according to Dummett-Gupta Oral Pigmentation Index scoring criteria given by Dummett C.O. in 1964 The investigators classified pigmented gingiva in patients as:
- Mild:Pink to slightly brown
- Moderate:Deep brown or black
- Severe:Mixed in color Score in each tooth was taken including one full inter dental papilla. Observations were made in natural light. The assessment of the scoring of the pigmentation index were done by all the three examiners, and the agreed upon score was assigned to prevent individual variations.
The investigators compared the intensity of pigmentation in each patient in recall sessions after 1month and 3mounth postoperative.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||19 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||Efficacy of810 nm Diode Laser on Gingival Pigmentation|
|Study Start Date :||April 2013|
|Actual Primary Completion Date :||January 2014|
|Actual Study Completion Date :||March 2014|
Experimental: 810 Diode Laser
810 nm Diode Laser, contact, continuous wave,320micron,
Device: 810 Diode Laser
The 810-nm diode laser has energy and wavelength characteristics that specially target the soft tissues. It has an affinity for hemoglobin and melanin, so it is an excellent soft tissue laser and is applicated for cutting and coagulating gingival tissue.Today,sparse studies have been published assessing physiologic gingival pigmentation using diode laser,therefore the aim of this study was to evaluate the effect of diode laser on the treatment of gingival pigmentation in adult patients.
- improvement of gingival pigmentation [ Time Frame: 1 month ]standard digital photographs were taken preoperative,1 month after laser therapy.
- changes in pigmentation based on standard digital photographs and index of Dummett et al. [ Time Frame: 3month ]standard digital photographs were taken 3 months postoperative.
